Symptomatic calcific tendinitis at unusual sites

Three cases of symptomatic calcific tendinitis at unusual sites (in the vastus lateralis tendon, the rectus femoris tendon and the flexor carpi ulnaris tendon) are presented. In two, the plain radiographs were nondiagnostic, and the diagnosis was made on the basis of the findings in computed tomography (CT) scans. The value of CT in examining atypical patients is demonstrated.
